Title: Throttle valve control device for engine
Inventor: OKUNO ITARU
IPC: F02D41/10
Filed: 1986-06-16
Abstract: PURPOSE:To secure a driving property suited to the driving inclination of a driver by taking in the operated quantity of an accelerator pedal as a required acceleration, correcting this value in accordance with a vehicle speed to obtain the final acceleration, and controlling the opening and closing of a throttle valve based on the final value. CONSTITUTION:A required acceleration alpha1 of a vehicle is calculated by a means C based on the operated quantity ACPb of an accelerator pedal A detected by a means B. And, the required acceleration a1 is corrected by a means E based on a vehicle speed Va detected by a means D, and the final acceleration alpha3 is calculated. Further, a throttle opening THO is calculated by a means F based on the final acceleration alpha3, while the opening and closing of a throttle valve H is controlled by a means G to obtain the calculated throttle opening THO. Thereby, the value of the required acceleration is set larger, the lower is the vehicle speed even with the same stepping quantity, securing a driving property suited to the inclination of a driver.

Title: Substrate and manufacture thereof
Inventor: ARITA MUTSUNOBU
IPC: H01L29/732
Filed: 1987-06-05
Abstract: PURPOSE:To prepare a device having high performance and a high function by depositing a single crystal insulating film, a lattice constant of which coincides with Si, onto single crystal Si. CONSTITUTION:SOI structure in which a growth layer 2 consisting of a single crystal insulating film, a lattice constant of which coincides with that of an Si substrate 1, is formed onto the Si substrate 1 is used. A parasitic P-N-P transistor is not shaped in the presence of the growth layer 2, the single crystal insulating thin-film. The SOI structure has an advantage where a latch-up phe nomenon which has been at issue in conventional bulk MOS transistors is not generated. Accordingly, the single crystal insulating film having high quality can be deposited onto Si, and a high-quality Si layer not misfitted can be hetero- epitaxial grown onto the single crystal insulating film.

Title: Tracking shift detector
Inventor: ITOU TAKASHI
IPC: G11B7/09
Filed: 1983-07-29
Abstract: PURPOSE:To detect stably a tracking shift by irradiating the light to a recording medium to which the binary information is recorded through a pit train, giving the photoelectric conversion to the reflected light from the recording medium to produce the 1st and 2nd signals and multiplying the 1st signal after smoothing the 2nd signal. CONSTITUTION:A light spot is irradiated to a discoid recording medium where binary information is recorded by a pit string, and the reflected light is received by a photoelectric conversion means 1 consisting of photodiodes D1-D4. An adder 2 adds the outputs of diodes D1 and D2; while an adder 3 adds the outputs of diodes D3 and D4 respectively. The outputs of adders 2 and 3 are applied to a voltage adder 4 and a differential amplifier 5. The outputs of the adder 4 undergoes waveform shaping and is used as an NRZ signal. The output of the amplifier 5 is applied to a smoothing circuit 11, and the delivered inverse IDL signal is applied to two switch circuits of a control means 12. The NRZ signal is applied to the means 12 from a waveform shaping circuit 6 in the form of a switch control signal. Then the means 12 gives the synchronizing wave detection to the inverse IDL signal and delivers a tracking error signal TE. Thus a tracking shift is detected with high stability.

Filed: 1989-06-02
Abstract: PURPOSE: To obtain an interferometer sensor in which the sum of interference spectrums related to temperature variation and pressure variation can be found using central and outer luminous fluxes being transmitted concentrically through an optical fiber. CONSTITUTION: At the time of operation, a sensor membrane 115 is subjected to pressure and temperature of a production pit and moved by a distance equal to the thickness of flat plates 13, 12 in response to the parameters thereof. Consequently, the stagger of luminous flux passing through a first interferometer along an optical path A in the vicinity of the axis of symmetry of sensor is varied as a function of the membrane 115. An annular luminous flux passing through a second interferometer along an optical path B is shifted over the distance between elements 16, 17. The distance is varied by the difference of expansion coefficient between respective elements as a function of temperature. Consequently, the stagger of luminous flux on the optical path B is varied.  Output lights from two interferometers are mixed at the inlet of fiber 113 and carries a stagger indicative of the moving distances 2e, 2e'.

Abstract: PURPOSE:To perform interlayer separation completely by a method wherein a polycrystalline silicon film is connected to a ground through a contact hole made in a second insulating layer in order to eliminate that an electric charge is accumulated in the polycrystalline silicon film. CONSTITUTION:A contact hole 7 is made in an oxide film 6; a polycrystalline silicon film 5 is grounded via a wiring part 8 through the hole 7. A wiring part is formed on a device isolation layer; a voltage is applied to the wiring part; when it is stopped to apply the voltage, an electric charge which has remained near an interface between the silicon film 5 and the oxide film 6 escapes to a ground via the wiring part 8. Accordingly, the electric charge is not accumulated inside the silicon film 5. In addition, a captured electron escapes to the ground via the wiring part 8. By this setup, an electric field is not generated between a silicon substrate 1 and the silicon film 5, thereby an inter-element isolation is executed completely.

IPC: H05K3/32
Filed: 1991-05-17
Abstract: PURPOSE:To reduce danger of short-circuiting in spite of a low pitch of connection electrodes, reduce contact resistance, and achieve low cost by setting a total of steps of the connection electrodes at 5mum or more, and setting a melt viscosity of binding agent for connection when it is heated at 10<7> poise or less. CONSTITUTION:Two circuit boards, in which a total of steps of connection electrodes 2, 3 to insulation plates 1, 4 in each circuit board is 5mum or more are connected to each other by heat and pressure using heat-binding binding agent 5 of which volume resistivity is 10<7>-10<18>OMEGA.cm, which includes thermosetting components, and of which lowest melt viscosity in heat application is 1X10<7> poise or less. The agent 5 flows between the electrodes, and though a micro- quantity of it is left between the electrodes, electric connection of low resistance can be achieved because of the volume resistivity of 10<18>OMEGA.cm or less. In addition, insulation can be kept to the adjacent electrode substantially because of the volume resistivity of 10<7>OMEGA.cm or more. Since conductive grains are not used, even in connecting the circuit board having low-pitch connection electrodes, danger of generation of short-circuiting by linkage of the conductive grains between the adjacent electrodes is eliminated, thereby the boards can e connected at a low cost.
